  • Patent number: 6105174
    Abstract: The male incontinence pouch allows the user to determine for himself whether he wishes to apply the pouch around the penis only or the penis and scrotum. The incontinence pouch has an outer liquid-proof polyethylene layer. A soft fibrous nonwoven material is attached to the polyethylene layer. An inner liquid-permeable material is applied to the nonwoven material. An absorption layer is disposed between the polyethylene layer and the liquid-permeable material to form a laminate. An edge portion of the liquid-permeable material is attached to another edge portion of the liquid-permeable material so that a cavity is formed therebetween at a short side surface of the incontinence pouch. The laminate is folded inwardly along a main folding line so that a side wall is formed, the side wall has an inside and an outside so that the inside has an outer base line and the short side surface has an inner base line.

  • Patent number: 4686939
    Abstract: A completely cooled fast fluidized bed boiler comprises a reactor (4) having a bottom section (3), an integrated primary non-centrifugal mechanical particle separator (5), a gas pass (7) containing convective heat exchangers (10), and means (6,8,9) for controllably recirculating separated particles into the reactor bottom section (3). Reactor (4), separator (5) and gas pass (7) are built as an integrated unit within one and the same cooling system. The boiler is controlled by maintaining the bed temperature substantially constant or within a relatively narrow temperature interval by regulating the recirculation rate dependent on boiler load. For regulating the recirculation rate a non-mechanical valve, preferably a so-called L-valve (8), is used.
